Mitsubishi Lancer Evolution's Innovative Intercooler Cooling System

Mitsubishi’s pioneering approach to intercooler cooling in the Mitsubishi Lancer Evolution series, particularly during the 1990s, remains a fascinating case study in Automotive engineering. The Evolution’s turbocharged 4G63 engine, a mainstay of rally dominance for ten generations, faced a significant challenge: the intense heat generated by the turbocharger.

Addressing Turbo Temperature with Direct Water Spray

Recognizing this issue, Mitsubishi implemented a remarkably effective solution – a direct water spray system integrated into the intercooler. Activated by a simple button within the cabin, the system would release a fine mist of water directly onto the intercooler, leveraging evaporative cooling to rapidly reduce the temperature of the compressed air.

Evolution of the System

Initially introduced in the 1995 Mitsubishi Lancer Evolution III (producing 270 CV), this system was refined over subsequent generations. Later iterations incorporated an automatic version, eliminating the need for driver intervention and activating only when temperature demands required. While other manufacturers explored alternative intercooler placements, Mitsubishi’s direct water spray proved consistently effective.

Legacy Continues in the Toyota GR Yaris

The legacy of this innovative cooling method continues today. The Toyota GR Yaris Aero Pack, a high-performance variant of the diminutive Japanese sports car, retains the original Mitsubishi system, demonstrating its enduring practicality and effectiveness. This testament to a solution developed decades ago highlights the ongoing relevance of clever engineering and problem-solving in the Automotive world.
